EPA: U.S. Greenhouse Gases Drop 1.6% from 2010 to 2011. The Environmental Protection Agency says that greenhouse gas emissions in the United States declined 1.6% from 2010 to 2011, continuing a trend that has seen greenhouse gas emissions fall 6.9% since 2005. The decline is mostly due to power plants switching from burning coal to natural gas which emits less carbon dioxide.
